This invention relates to terminal studs for electrical apparatus, andconsists, broadly stated, of a metallic member adapted to receive abinding screw, or having threaded shank formed integral there. receive abinding post, and being embedded. in a block of insulating materialwhich is permanently secured to an externally screwthreaded metallicsleeve.

The main. object of my invention t prd 'vide a device in which none ofthe parts can Work loose and which is notliable to turn or work out ofthe support to which it. is connected.

Another object of my invention. is to provide a device that presents aneat and orna mental appearance and. which is oi simple construction sothat it can be manufactured at a small cost.

Referring to'Figs. 1 to l oi the dr which represent the preferred iorntol K vention, 1 designates a non-circi-ilar metallic member'preferablyof hexagon. l shape provided with an internally screw eaded btnc thatreceives the binding screw h r end of said member having a tubuuextension 3 into which one of the ccnnu ting wires 4 extends and issoldered.

her l embedded in a block 5 of insulating material, pre 'erably hardrubber, and said block is arranged inside of an externallyscrew-threaded metallic sleeve 6 to which it p is permancnelv connectedpreferably by l? olding the insulating material inside of the eve andaround the metallic member 1, the sleeve 6 heing preferably providedwith notches 6" in its upper edge so as to connect it more securely tothe block 5.

The block is provided at its upper end with ahead or enlarged portion 7having a milled or corrugated periphery which enables the de -rice to bescrewed into the support 8 to whic i it is connected the underneath sideof the head contacting with the upper face of the support, as shown inFig. 1. The memher 1 is provided at its upper end with a ciriace cl saidblock so that a very neat and or' nil-mental cimstruction is produced.

it is impossible for'the metallic member to turn in the block 5 onaccount of its noncircular shape, and the screw threads on the exteriorof the sleeve 6 to prevent the device i'rom turning in die support inwhich it is mounted, the opening. in. the support into which the deviceis screwed being preferably coated with ceneu "or some adhesive.

. Consequently, none of the parts of the device can work loose and thedevice itself cannot appearance and as it is of very simple constructionit can be n'ianufactured at a small cost.

Having thus described my invention, what 2. A device of the characterdescribedcomprising a central metallic member adapted to receive abinding device. and provided at its lower end with a reducedtubularshaped portion and at its upper end with a collar, and a block ofinsulating material in which said member is embedded, the top face ofsaid block being flush with the shoulder prodncedby forming the collaron the upper end of said member and the tubular-shaped portion at thelower end of said member projecting beyond the bottom face of saidblock; substantially as described.

3; A device of the character described comprising a central metallicmember proat its lower end to receive a conducting wire,

a block of insulating material surrounding said member and provided atits upper end with an enlarged portion, and an externally screw threadedsleeve surrounding the lower portion of said block; substantially asdescribed. Y

4. A device of the character described comprising a non-circular memberadapted to receive a binding screw,. a block of insulating materialsurrounding said member and provided with an enlarged head, atubularsha-ped portion on the lower end of said member which projectsbeyond the bottom face of said-block and is adapted to receive aconducting wire, a circular collar on'the upper end of" said memberprojecting beyond the top face of the block, a washer surrounding saidcollar, and an externally screw-threaded sleeve surrounding the lowerportion of said block; substantially as described.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses, this fifth day of January 1907.
